Thanks for reaching out. Please click on the drop down beside 'Here's why your channel wasn't approved for monetization' & then share a screenshot of that page. Also, were you a part of YPP earlier & now demonetized, or is it that you've applied now & were rejected? Let us know.
Thanks for the screenshot. This typically means that the content in your channel is not original/ is auto-generated. You can always make necessary changes and reapply for YPP again in 30 days. Learn more about reused content here: https://goo.gl/E5dgGo . Hope this helps.
